Abstract
The invention relates to a reverse-circulation slag-removal reamer bit which comprises a reaming device and a jet slag sucking device. The reaming device comprises a bit body, a cutting device and a guiding device, and the cutting device and the guiding device are fixed on the bit body; a jet pipe is arranged in the jet slag sucking device, an inner nozzle is fixed to the right end of the inside of the jet pipe, a throat cavity and a diffusion cavity are arranged at the left end of the inside of the jet pipe, a slag sucking pipe is fixed to the middle of the jet pipe, one end of the slag sucking pipe is communicated with the jet pipe, and the other end of the slag sucking pipe is close to the cutting device; and slag delivery pipes or a rear drill stem and a front drill stem are respectively hermetically fixed to the left end and the right end of the jet pipe. The reverse-circulation slag-removal reamer bit is simple in structure, convenient to use, free of environmental pollution and low in cost. Besides, when the reveres-circulation slag-removal reamer bit is used for construction on rock stratums, slag can be removed by clear water without mud.
Description
Technical field
The present invention relates to a kind of non-excavation reaming bit.
Background technology
While constructing along with development, particularly well, pile foundation, diaphragm wall, the mine shaft of production, science and technology, employing direct circulation row landwaste, sprays into water by drilling rod or mud makes the landwaste boring discharge along holing.This is not only without dying environment, and swell soil that need to be a large amount of, and expense is high.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of reverse circulation cutting cleaning reaming bit, it is simple in structure, easy to use, free from environmental pollution, and use cost is low.
The present invention solves the technical scheme that its technical problem takes: it comprises Counterboring apparatus and jet dreg inhaling device, and Counterboring apparatus comprises bit body, topping machanism and guiding device, fixedly topping machanism and guiding device on bit body; Described jet dreg inhaling device has jet pipe, and the right-hand member in jet pipe is inner nozzle fixedly, and the left end in jet pipe has cavum laryngis and diffusion chamber, and the middle part of jet pipe is dreg inhaling pipe fixedly, and dreg inhaling pipe one end communicates with jet pipe, and the other end is near topping machanism; The two ends, left and right of described jet pipe seal respectively fixedly slag-transporting pipe or rear drilling rod and front drilling rod.
The present invention has a little following: the boring mud that 1), generally drill bit can be discharged when using 60s mud is less than 10mm, and the present invention is slightly less than the diameter of scum pipe with the cobalt slag that clear water is discharged.If use 140 drilling rods, the nearly 100mm of deslagging diameter.Because boring mud does not repeat fragmentation, drilling efficiency can improve 4-6 doubly; 2), while constructing in lithostratigraphy, without mud, as long as just can deslagging with clear water.General drill bit construction and installation diameter 1016mm, the pipeline that length is 1000 meters, approximately will use 600 tons of swell soils.Approximately more than 60 ten thousand yuan of expenses; 3), in construction progress, without running, emit mud phenomenon, save the expense of processing useless slurry; 4), clear water construction is conducive to protection of the environment; 5), because deslagging in hole is timely, in hole, there is no boring mud wearing and tearing drill bit, greatly extended the application life of drill bit; 6), in hole scarfing cinder clean, reaming to the 1.2-1.3 of caliber doubly, does not need the hole clearly just can trombone slide.And prior art be will diffuse into 1.5 times of caliber time, 2-3 time, clear hole, can trombone slide.This expense can be saved many ten thousand yuan of 20-30.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is first embodiment of the invention schematic diagram;
Fig. 2 is second embodiment of the invention schematic diagram;
Fig. 3 is third embodiment of the invention schematic diagram;
Fig. 4 is fourth embodiment of the invention schematic diagram.
The specific embodiment
As shown in drawings, the present invention includes Counterboring apparatus and jet dreg inhaling device, Counterboring apparatus comprises bit body 4, topping machanism 5 and guiding device 8, fixedly topping machanism 5 and guiding device 8 on bit body 4; Described jet dreg inhaling device has jet pipe 2, and the right-hand member in jet pipe 2 is inner nozzle 7 fixedly, and the left end in jet pipe 2 has cavum laryngis 3 and diffusion chamber 11, and the middle part of jet pipe 2 is dreg inhaling pipe 6 fixedly, and dreg inhaling pipe 6 one end communicate with jet pipe 2, and the other end is near topping machanism 5; The two ends, left and right of described jet pipe 2 seal respectively fixedly slag-transporting pipe or rear drilling rod 1 and front drilling rod 10.
The outer stationary annular nozzle 12 of described jet pipe 2, in nozzle ring 12, there are oblique spray orifice 13 and mozzle 15, oblique spray orifice 13 and mozzle 15 communicate with jet pipe 2, the fixing dreg inhaling pipe 6 communicating with jet pipe 2 on jet pipe 2 between oblique spray orifice 13 and mozzle 15 imports, the interior fixing seal plate 14 of jet pipe 2 between dreg inhaling pipe 6 and mozzle 15 imports, passes through in the cavum laryngis 3 and diffusion chamber 11 of mozzle 15 by oblique spray orifice 13 stream penetrating pipes 2 water under high pressure in front drilling rod 10.
Described jet dreg inhaling device is fixed in the centre bore of Counterboring apparatus, compact conformation.As shown in Figure 1,3.
Described jet dreg inhaling device is fixed on the rear side of Counterboring apparatus, and negative pressure is large, slag absorbing better effects if.As shown in Figure 2,4.
On described inner nozzle 7, have axial spray orifice 9, axially spray orifice 9 quantity are 1-3.
On described nozzle ring 12, have oblique spray orifice 13, oblique spray orifice 13 quantity are 3-6.
During use, it is mobile that drilling rod 10 pulls Counterboring apparatus and jet dreg inhaling device to enter in hole to be expanded forward (in figure to the right), and under the effect of guiding device 8, Counterboring apparatus is by front drilling rod 10 driven rotary reamings.Counterboring apparatus cuts under the negative pressure that Buddhist nun's slag of getting off produces at the interior high-velocity flow of front drilling rod 10, sucks and is pulled away, by slag-transporting pipe or 1 discharge of rear drilling rod from dreg inhaling pipe 6.
